− An important element of towing planning is
establishing a method of communication and
cooperation regarding management of the tow.
− An equally important element of the towing plan
is risk assessment of towing process.
− The level of towing risk throughout the entire
towing operation depends on the following
elements :
1 Quality planning of the route of the tow.
2 Quality and reliability of communication in the
tow and outside the system.
3 Good supervision of the operation (operation
management).
4 Experience of tug crews.
5 Technical condition of tugs (towlines, winches,
engine power, etc.)
6 Lack of commercial pressure on the tugs crews
from outside.
7 Unexpected changes in the marine
environment, such as sudden changes in
weather (high seaways).
8 No unexpected increase in ship traffic along the
towing route.
9 Area free from pirate attacks.
ANNEX
Basic safety elements of the towed ship
Prior to towing operation, the towed vessel must
meet certain technical parameters in order to be
accepted on the tow in order to move from position A
to position B.
1 Training the crew in the safe operation of technical
systems related to the tow.
2 Before towing, the vessel must prepare lights and
signs prescribed for towing.
3 The vessel must have a specified draft (trim) for
the entire towing period.
4 The towed vessel must be watertight (when
making heavy weather).
5 The towed vessel must have a well secured cargo
(ballast water with no free space) etc.
6 The towed vessel must have safe stability in all
wave conditions and external disturbances.
7 Steering system, propeller (the rudder to be held in
the forward and aft position- midships). If
possible, the propeller should be secured against
turning.
8 Details on the technical and operational condition
of the ship should be collected on an ongoing basis
and ready to be reported.
9 Weather forecasts and sea state are to be
controlled. The captain must establish constant
contact with the mainland (shipowner, SAR, etc.).
10 Special Towing Booklet throughout the entire
towing passage must be kept.
